POSITIONING OF THE ATOM
The Transmitters emit low frequency signals that radiate outward in semicircular patterns
that are parallel to the length dimension of the Transmitter. A coiled antenna inside the
ATOM receives the signals when it is positioned within a zone parallel to or at a 45 degree
angle to the Transmitters as shown on page 88 Figure 78.
The ATOM cannot effectively receive a signal when it is held out to the sides of the
Transmitter(s) or held at distances greater than 6 feet (2 meters) in front of the Transmitter(s).
Best reception is achieved when the ATOM is within 3 feet (1 meter) of the Transmitter(s).
When installed into the high pressure ports of the Regulator First Stages, the Transmitters
must be positioned so that they face horizontally outward from the Tank Valves.
Link Interruption Underwater
During a dive, you may at times move the ATOM out of the
signal pattern of the Transmitter, resulting in a temporary interrup-
tion of the Link signal.
An interruption lasting greater than 15 seconds will cause the
Tank Pressure value to flash (on Alternate Display 1), the Link icon
to flash, and the Audible Alarm to sound (Fig. 79). The Link will
be restored within 4 seconds after the ATOM is moved back into
its correct position.
